The Ekpyrotic Scenario

From the wikipedia article:
The ekpyrotic universe, or ekpyrotic scenario, is a cosmological model of the origin and shape of the universe. The name comes from a Stoic term for “out of fire”.[1] The ekpyrotic model of the universe is an alternative to the standard cosmic inflation paradigm, both of which accept that the standard big bang Lambda-CDM model of our universe is an appropriate description up to very early times. The ekpyrotic model is a precursor to, and part of the cyclic model.
